An online tabletop that gets out of the way. Your books, your notes, your maps — all in one place. Nothing to install. Nothing to configure. Just the game.
You came to play.
Everything you need. Nothing you don't.
Maps and Tokens
Upload a map. Place your tokens. Play. Drag to move, scroll to zoom. Easy grid editing when you need it — just your map and your minis.
Character Sheets
Use the built-in sheets or build exactly what your system needs with the SDK. Mothership, Blades in the Dark, your homebrew — every system gets a real sheet, not a workaround.
Your PDF Library
Upload your rulebooks, adventures, and supplements. Search them during play. Reference any page from anywhere in the app. Your books, always at the table.
And more
Dice
3D physics dice. Any notation. Roll from anywhere.
Notes
Campaign prep, session logs, world lore. Rich text, tags, search.
Encounters
Track initiative, manage turns, run combat.
Chat
Messages, dice rolls, and game events in one thread.
In the time it took to read this far, you could be rolling dice.
The Experience
Sit down and play.
You open a game. Your players join. You play. That's the whole onboarding.
First time running a game online? You'll be ready in minutes. Already have a campaign somewhere else? Bring it over — your PDFs, your notes, your prep all come with you.
Works on your phone, your tablet, your laptop. Every feature, every device.
